>>C<< STEERING WHEEL ASSEMBLY/AIR BAG
MODULE ASSEMBLY INSTALLATION

CAUTION

When installing the steering wheel and air bag module,
ensure that the harness of the clock spring does not
become caught or tangled.
1. Before installing the steering wheel and air bag module, turn

the vehicle’s front wheels to the straight-ahead position and
align the mating marks of the clock spring.

2. After securing the steering wheel, turn the steering wheel all

the way in both directions to confirm that the steering wheel
rotation is normal.

.

>>D<< POST-INSTALLATION INSPECTION

1. Reconnect the negative (

−) battery cable.

2. Turn the ignition switch to “ON” position.
3. Does the "SRS" warning light illuminate for approximately

seven seconds, and go out?

4. If yes, the SRS system is functioning properly. If not, refer to

P.52B-31

.

AIR BAG MODULE CHECK

DANGER

Never attempt to measure the circuit resistance of the
air bag modules (squib), even if you are using the
specified tester. If the circuit resistance is measured
with a tester, accidental air bag deployment will
result, and possible serious personal injury.

WARNING

If any component damage is found during the follow-
ing inspection, replace the air bag module with a new
one. Dispose of the old one according to the specified
procedure. (Refer to

P.52B-387

).

1. Check the pad cover for dents, cracks or deformation.

2. Check the connectors for damage, the terminals for

deformation, and the harness for binding.

3. Check the air bag inflator case for dents, cracks or

deformation.

4. Install the air bag module (driver’s side) to the steering

wheel and check fit and alignment with the steering wheel.

5. Install the air bag module (front passenger’s side) to the

instrument panel and front deck crossmember and check fit
and alignment.

FRONT SEATBACK ASSEMBLY WITH
SIDE-AIRBAG MODULE CHECK

DANGER

Never attempt to measure the circuit resistance of the
air bag module (squib), even if you are using the
specified tester. If the circuit resistance is measured
with a tester, accidental air bag deployment will
result, and possible serious personal injury.

WARNING

If any improper part is found during the following
inspection, replace the front seatback assembly with
a new one. Dispose of the old one according to the
specified procedure. (Refer to

P.52B-387

).

1. Check the air bag module deployment section for dents or

deformation.

2. Check the connector for damage, the terminals for

deformation, and the harness for binding.

CLOCK SPRING CHECK

If any malfunction is found in the following inspections, replace
the clock spring with a new one.
1. Check the connectors and protective tube for damage, and

the terminals for deformation.

2. Visually check the case for damage.

3. Check to see that there is a charge (continuity) between the

C-306 clock spring connector terminal 1 and C-304 horn
switch.

CAUTION

Do not directly insert a probe, etc. into the terminal from
the front of the connector.
4. Insert the special tool (MB991222) from behind the airbag

module connector of the C-305 driver's side.

5. As shown in the figure, connect the circuit tester to the

special tool (MB991222) and check to see that there is a
continuity between the terminals.

SIDE IMPACT SENSOR

M1524004600317

REMOVAL AND INSTALLATION

A side impact sensor is installed behind the center pillar trim on both driver and passenger sides of the vehi-
cle.

WARNING

•

Never attempt to disassemble or repair the side impact sensor. If faulty, replace it.

•

Do not drop or subject the side impact sensor to impact or vibration. Replace the side
impact sensor, if dents, cracking, deformation, or rust are present.

•

Replace the side impact sensor after the air bag has deployed.

NOTE: The illustration above shows the side impact
sensor (RH). The position of the side impact sensor
(LH) is symmetrical to this.

Pre-removal Operation
• Turn the ignition key to the "LOCK" (OFF) position.
